1) In Calibration Tab mode, click “Calibration Mode” button. This will allow temporary manual control of actuator for setting new
pilot control limits. These values will then be sent to actuator at completion of calibration. Check that actuator LED is
blinking red/green during calibration mode process. All High and Low point settings steps must be completed in order
shown. Use the cancel button to input new values.
2) Look at pressure gauge or flow sensor, use Increase actuator or Decrease actuator buttons until desired LOW pressure or
flow point (same value used in Configuration tab window and showing in Low Point window) is reached. Press Stop
actuator button to stop actuator. Use good quality gauges and be as precise as possible. If calibrating CDHS-32 for flow
rate using an orifice plate, a calibrated differential pressure gauge or transmitter is recommended.
3) Once desired low pressure or flow is reached and actuator is topped, click Low point setting button.
4) Look at pressure gauge or flow sensor, use Increase actuator or Decrease actuator buttons until desired HIGH pressure or
flow point (same value used in Configuration tab window and showing in High Point window) is reached. Press Stop
actuator button to stop actuator.
5) Once the high pressure or flow is reached and actuator is stopped, click High point setting button.
6) Finally, click Download calibration button to store values in actuator. High point, Low point, Loss-of-Signal, and Rotation
speed settings are sent to actuator. Actuator LED will change to green when complete. Unplug cable from actuator and
replace protective cap. 130VC-2 Actuator is now ready to accept 4 - 20 mA command signal from permanent cable Yellow
and Black wires.
